New Mercedes-AMG '53' models launched
435hp electrified AMGs revealed, with two E-Classes and a CLS kicking the range off
Launched initially as a CLS53, E53 Coupe and E53 Cabriolet, the new cars usher in electrified turbos for Affalterbach products. So they use a twin-turbocharged 3.0-litre straight-six, but one of the turbos is an electric compressor - technology similar to that used in the Audi SQ7. An EQ Boost starter-alternator supplies the 48v onboard subsystem (which then powers the compressor, and supports the gliding mode and stop-start) as well as providing an additional 21hp and 184lb ft. Described as the "first step towards a hybridised future" by AMG, the turbo arrangement should help eliminate lag - working until the big, old fashioned turbo is spinning - and also reduce fuel consumption.
Power reaches all four wheels via the nine-speed 'AMG Speedshift TCT' automatic, promising "very responsive" behaviour whether using the paddles or left to its own devices. The familiar Mercedes drive modes - Eco, Comfort, Sport, Sport + and Individual - feature, with standard AMG Ride Control+ air suspension, plus new steering knuckles, more rigid elastokinematics and more negative camber at both axles. There's continuously adjustable ADS+ damping (with three characteristics) as well. And pneumatic self-levelling. So if your 53 is pitching, rolling, or displaying any movement whatsoever, something is probably wrong.
Steering is electro-mechanical and speed sensitive, with braking provided by 370mm ventilated front discs and 360mm ventilated rears. Weight is from 1,895kg for an E53 4Matic+ Coupe (without a driver), through 1,905kg for a CLS and 1,980kg for an E53 cabrio.
The usual Mercedes loveliness abounds inside, with the 53 also benefitting from an AMG Performance wheel, AMG badges and new seats. There's no word yet on a seven-seat E53 estate, however...
Mercedes has shown its range of 53 models off to the world at Detroit, so keep a look out for them in the shadow of the G-Class somewhere. Expect full UK prices and specs in due course too, with sales imminent. The AMG family continues to grow!
